HENRY DAVID BIRDS WALL,

METAL BOX.

SPECIFICATION forming part of Letters Patent No. 368,985, dated August 30, 1887.

Application filed May 11, 1887. Serial No. 237. 94. (No model.) Patented in England March 6, 1886, No. 3,185.

.To all whom it may concern.-

Be it known that I,- HENRY DAVID BIRDS WALL, a subject of the Queen of Great Britain, and a resident of the city of Liverpool, England, paint, color, and varnish manufacturer, have invented new and useful Improvements in Metal Boxes, (for which I have obtained a patent in Great Britain, No. 3,185, bearing date March 6, 1886,) of which the following is a specification, reference being had to the accompanying drawings, in which Figure 1 is a sectional elevation of a metal box with the improvements according to my invention applied thereto. Fig. 2 is a plan of the box shown at Fig. 1. Fig. 3 is asectional elevation of a metal box shown with a modification of the improvements according to my invention applied thereto. Fig. 4 is a plan of the box shown at Fig. 3. Fig. '5 is a sectional elevation of a metal box shown with another modification of my invention applied thereto. Fig. 6 is a plan of the box shown at Fig. 5.

The object of my invention is to provide a means for connecting or securing lids of metal boxes or cases for holding paints, colors, oils, varnishes, and other substances so that such lids can be easily removed; and at the same time offer no extraneous projections to endanger the lids being removed by accident.

Boxes of the class to which my invention relates have hitherto'mainly been constructed with their lids soldered to their body. This practice, however, although inexpensive, necessitates the use of a cutting instrument to open the box.

According to my invention I construct the cover of the box as follows: Within the upper rim of the box I provide a ring, which is attached to the rim of the box in any suitable manner, soldered or otherwise. The inner edge of this ring is turned down. The lid or bung consists of a dished piece of metal corresponding in size with the inner-diameter of the ring and fits therein. Round the edge of the lid there is a narrow flange, which, when the lid is in position, lies closely over the upper surface of the ring. Across and connected to the lid I provide a metal barthe ends of which project slightly over the lid and rest on the ring, to which they may be attached by solder. The lid is removed by first disturbing the soldered connections of the bar and then using the baras a handle, by which the lid can be withdrawn;

In the drawings, a designates the box, within the upper rim, a, of which there is provided a dished or sunk ring, I), which is soldered or otherwise attached to the said upper rim, a, in any suitable manner. The inner edge, e, of this ring b is turned down.

(1 is the lid or bung of the box a. It consists of a dished piece of metal corresponding in size with the inner diameter of the ring 12. Round the edge of the lid d there is a narrow flange, e, which, when the lid (2 is in position, lies closely over and in contact with the upper surface of the ring I).

Across and, connected to the lid cl, I provide a metal bar, h. The ends of this bar It project over the lid 01 and rest on the ring I), preferably on the bevel-rim of the ring I), as shown in the drawings. The metal bar It is attached to the lid (2, preferably by being cranked down at h, and fastened to the lid (1 by soldering, the ends of the bar It being fastened to the bevel-rim of the ring 6 by solder, as shown at Figs. 1 and 2 of the drawings.

Instead of fastening the bar it to the lid d, as shown at Fig. 1, it may be fastened by being bent round at h, and soldered to the center of the lid (1 in the manner shown at Figs. 3 and 4; or the bar h may be fastened by simply soldering it to the flange eat 71/; or metal loops h attached to the lid, preferably, by solder, may embrace the rod h, and so make it fast to said lid; or both solder and metal loops may be employed for this purpose in the manner shown at Figs. 5 and 6. The bar it serves as a handle for removing the lid. (2, and it also serves when soldered to the ring b to keep the lid in position.

To remove the lid (2 from the box a the soldered connections between the bar h and the ring 15 are first broken or disturbed. The lid (1 can then be removed by using the bar It as a handle.

Abox and lid constructed as above described is inexpensive and has no objectionable projections beyond the rim of the box. The bar 71, soldered to said lid and to the ring I), the said bar lying below the level of the upper rim, a, of the box, substantially as and for the purposes set forth.
